Golden Tropical Freshwater Mussel (Pilsbryoconcha exilis)

Overview

The Golden Tropical Freshwater Mussel is a striking bivalve known for its smooth, elongated shell with a warm golden-bronze sheen. It is a natural filter feeder that helps polish aquarium water by removing microscopic particles. Best suited for mature aquariums with stable parameters and plenty of suspended micro-food.

Origin

Native to Southeast Asia, particularly Thailand and surrounding regions. Found in slow-moving rivers, ponds, and floodplains with soft, silty substrates.

Feeding

A pure filter feeder that consumes:

• Suspended microorganisms

• Phytoplankton

• Infusoria and microfauna

• Fine detritus

Because aquariums often lack enough natural micro-food, supplemental feeding may be required using products such as liquid phytoplankton, green water, or micro-sized planktonic foods. Avoid overfeeding—poor water quality is the main risk.

Tank Mates

Peaceful but requires gentle companions, such as:

• Small tetras and rasboras

• Peaceful gouramis

• Corydoras species

• Shrimp

Avoid:

• Loaches

• Puffers

• Crabs

• Large cichlids
  All of these may nip, pick at, or disturb the mussel.

Aggression

None. The species is completely passive.

Experience Level

Intermediate to advanced. Mussels require stable, mature tanks with a steady food supply and excellent water quality. Improper care can lead to starvation in clean or newly established aquariums.

Water Parameters

• Temperature: 72–82°F (22–28°C)

• pH: 6.8–7.8

• Hardness: 4–15 dGH

• Notes:

  • Needs soft to medium substrate to safely burrow.

  • Very sensitive to ammonia and nitrite—requires pristine water.

  • Should not be placed in tanks with strong flow.

The Golden Tropical Freshwater Mussel (Pilsbryoconcha exilis) is an eye-catching and functional filter feeder that thrives in stable, mature aquariums with peaceful tank mates and a consistent supply of micro-food.
